8.1.1 Comparator Inputs

The TLV3201 and TLV3202 are rail-to-rail input comparators, with an input common-mode range that exceeds the supply rails by 200mV for both positive and negative supplies. The devices are specified from 2.7V to 5.5V, with room temperature operation from 2.5V to 5.5V. The TLV3201 and TLV3202 are designed to prevent phase inversion when the input pins exceed the supply voltage. Figure 8-1 shows the TLV320x response when input voltages exceed the supply, resulting in no phase inversion.

The electrostatic discharge (ESD) protection input structure of two back-to-back diodes and 1kΩ series resistors are used to limit the differential input voltage applied to the precision input of the comparator by clamping input voltages that exceed VCC beyond the specified operating conditions. If potential overvoltage conditions that exceed absolute maximum ratings are present, the addition of external bypass diodes and resistors is recommended, as shown in Figure 8-2. Large differential voltages greater than the supply voltage must be avoided to prevent damage to the input stage.
